Referring now to the drawings in which like characters of referencedesignate corresponding parts, throughout the several views, the numeral1 designates ghe panel of .trimming material that is attach d by meansof the fasteners 2 to the sheet metal framework 30f a vehicle body. Asshown, each.

fastener preferably consists of a headed pin 4 and a cooperating socketmember 5. Each pin is provided with a long shank and a relatively largehead 7 while each- \socket'member preferably consists of a hollowcup-shaped body 8 having a restricted neck 9 and a marginal flange 10.In order that the socket members may receive and hold the shanks 4 ofthe pins, the body portions 8 are provided withcentral openings 11 andthe radial slits 12 thereby providing prongs 13 for engagement with theshanks 6 of the pins.

In order that a minimum number of fasteners will be required to attachthe trimming material to the framework, I preferthe inner face of thebacking at the edges thereof by relatively small tacks 16 and areprovided at their outer edges with longitudinally extending flanges 18that cover the;

edges of the backing.-

In the process of construction, the shanks I 6 of the pins are firstdriven through the backing 14, then the strips 15 are secured to thebacking by means of the tacks 16, whereupon the trimming material 1 isplaced over the backing and strips and is folded around the. flanges 18at the edgesof the backing and is secured to the oppositerside of the"backing. The trimming materialiim'ay cooperating socket members whichwill gri the shanks firmly so that the backing 14 an trimming materialwill be held securely in position.

In this connection it will be noted that then be attached to theframework of the vehicle body by merely pressing the shanks 6 1 of thepins between the prongs 13 of the the diameter of each socket member ismuch larger than the cross sectional area of each pin shank, hence thepins may be pressed into locking engagci'nent with the prongs of thesocket members while disposed at an angle thereto. This would occur whenthe pins and socket members were not in registration when the trimmingmaterial is applied to the frame work. Thus this freedom of angularmovement of the pin shanks in the socket members will automatically takecare of such irregularities in assembly.

In Figures 5 and 6 I have shown a slight ly modified construction inwhich the shanks 6 of the pins are driven through openings 20 in themetal strips 15 as well as through enlarged openings 21 in the backingll. In this construction the strips 15 are preferably provided aroundthe openings 20 with radial slits 22 thereby providing prongs 25 whichare pressed into the openings 21 in the backing by the heads 1' of thepins as shown in Figure 5 of the drawing so that the outer surfaces ofthe heads will be substantially flush with the outer.

surfaces of the strips. In Figure 7 I have shown another modification inwhich the backing is preferably a channel-shaped strip 30 of light gaugemetal. This form of backing is preferably used when it is desired toattach the trim-' ming material to posts 31 or narrow portions of thevehicle body framework. Vith this construction the shanks 6 of the pinsare preferably driven through suitable openings 32 in the base of thechannel and are adapted to be held securely in position by means of theprongs 33 of the cooperating socket members 34 which correspond to thesocket members 5. As shown, the bases of the channel-shaped strips 30are preferably provided around the openings 32 with radial slits 35 toprovide prongs 36 which are pressed inwardly by the heads of the pins asshown in Figure 6 of the drawing so that the outer surfaces of the headswill be fiush with the outer surfaces of the bases of the channel-shapedstrips.

As shown in Figure 7 of the drawing, the trimming material 1 concealsthe heads of the pins and is preferably folded around the flanges 37,and is secured to the inner sides of the bases of the channel-shapedstrips. Thus, when the shanks 6 of the pins are pressed between theprongs 34 of the socket members the flanges 37 will provide straightedges for the trimming material and will hold the latter against theframework of y the vehicle body.

In Figure 8, I have shown another modified construction in whichtheframework 40 of the body is preferably provided with spaced openings 41and radial slits 42 providing prongs 43 which are adapted to grip theshanks'a l-of the pins'instead of the prongs of the socket members shownin Figure 7 of the drawing.

In Figures 5) to 15 inclusive 1 have shown another modification in whichthe shanks -15 of the pins it; are provided with substantiallyfrustro-conical serrations 47 which are adapted to' be engaged by theprongs 18 of the socket members 19. IVith this construction the metalbacking strips 50 are preferably provided with embossed or counter-sunkportions 51 for receiving the beveled portions 52 of the heads of thepins .46 and are provided with struck-out tongues 53 that. arepreferably bent over the flat surfaces 51 of the heads of the pins 46 tosecure the latter to the backing strips 50 as shown in Figures 13 and14; respectively of the. drawings.

In Figures 16 and 18 I have shown still another modification wherein thesocket member 60 is formed of two sections 61 and (32 respectively. Asshown, the section 61 corresponds to the socket member 5 except that theflange 63 thereof is preferably crimped over the flange (3 1 of thetubular section 62. This form of fastener is preferably although notnecessarily, employed to hold suitable screws 65 which are used tosecure trimming material suchas strips of channelmolding 6G. to themetal fr:: nework 67 of the vehicle body. Thus, with this construction,the screws 65 are inserted through suitable openings 68 in the molding6(5 and are driven between the prongs 69 of the socket member 60. Theseprongs (39 will effeitively hold the screws 5 while the tubular section62 will maintain the shanks of the screws in centered position relativeto the prongs.

In Figure 17 the socket.- mcmber 70 is similar to the socket members 5and is provided with prongs 71 which are adapted to engage and hold thethreads 72 on suitable screws 73 used to secure the trimming material orother article (not. shown) to the metal framework of the vehicle body.IVith this construction, the screws 72 are adapted to engage the prongs71 on an angle as shown by dotted lines in Figure 17 so that thetrimming material. molding. etc. may 3 be readily attached to the metalframework of the body even though the socket member may be spaced apartimproperly in the framework. or for any other reason the screws might beout of alignment with the socket members when the trimming material.etc, is applied to the framework.

From the foregoing description it will be readily apparent that I haveprovided an extremely simple fastener that can be manufactured at acomparatively low cost and which will permit the trimming material to beeasily and quickly attached to metal strips or. channelswill strengthenthe construction in: addition to providing straight edges for the foldsof the trimn'iing material. Inasmuch as the trin'nning; material isprovided with a backing or still'ening member, the fasteners may bespaced further apart sothat only a few are required to secure thetrimming material to the body framework.

lVhile it is believed that from the foregoing description, the natureand advantages oi the invention will be readily apparent, I desire tohave it understood that I do not limit myself to ,what is herein shownand described and that such changes may be resorted to when desiredast'all within the scope of what claimed.
